.Referring tov the drawings wherein'like numerals designate like parts, it can beseenl that Figs; letto 18 inclusive clearly show the type and construction of the radiator .which this'machine is adapted to produce.

By referring to Fig.- 17, and starting at the"V F rwound and' from'which itis paid tothe punching' device." This punching ydevicer which' 'can rbe of 'conventional construction is brieiiy described and disclosed in Fig. 2

andgenerally referred yto by numeral 6.' This f punchi'ngf'and forming device 6, Viirst forms the'flange Galongone longitudinal edge of the strip l5y and simultaneouslyforms the T shaped slot 7, dividing the/"strip-into' sections 8 and simultaneously forming. the lflanges 9 which' are dispo'sed'laterally lfromthe same,v side `of 'the strip ,5. It can be plainly geen in Figs. 14,;'15 "and, 16,' that the flangey 6 engages the radiator;tub'elOlPand'is at the headof each slot 7 -forf`engagenent over the correspond! ing edge portion of the tube 'y 10,. while the flanges 8 abutl each other inl-the manner shown vin Figs. lliand 16 to provide substantially' closedpassageways l1 between'the sections 8.

l\ToW referring to the details of the machine, it can-be seen that the machineincludes a frame generally referred to 4 by'numeral 12, VWhich includes' the side rails 13-14, spaced vbythe spacing members 15. Figsil and 3 show that the side; rai ls 13 and v14 of the frame A12 are supported by the legs 16 at the ends and-intermediate portions thereof.v

' vBrackets 17-517 project froi'n'certain of the Ylo - Can-1 also; beu seen in; Eig.2;that the Geneva- Vlegs 16 (see Figs. 2 and 3) anfdhave bearings `18 at .their outer end-s"throughfvvhiclilthe` .shaft 19 is journalled. f Thisfshaft 19 carries Vthe p ulley 20 over which the drive belt 21 (see Fig. 3) is trained, and asprocket'vvheel 22, over Which the vchainl 23 is trained.. It

and this' WillV be taken after.;

As can be clearly shown in Figs. 1 and3, a second shaft 25 is journalled through bearings 26 on the arms'27, projecting' from eeru'p in detail herein- 'tainofthe legs-16. VAs is clearly shown in meshing With'abevel gear 30` located yonthe f Figs; 3 ,this shaft 25 carries la sprocket 28 overgvvhich the!.aforementioned chain 23 is trained, and at this point-it can'beseenthat the shaft is driven by the shaft 19through this sprocket andchaindrive.

The shaft- 25 alsocarries a bevelgear 29 lower end ofthe shaft 31. This shattv 31. is

journalled through a barrel32 supported by the bracket 33 (seeFig. 3) The upper end ofthis shaft. 31 is equipped with a bevel gear 34 .Which is meshablewith either one of ther twoconnectedfbevel gears 35436,. splined to theshaft 37 as, at 38 (see Fig .j13 .1, v

By referring 'to Fig.2,itcan be seen that numeral 85 represents the reel lon which the strip 5 is wound and from which the same is paid through the punch press 6. I It can now be seen that when the belt 21 1.(see/F ig. 3) is in operation,power is transmittedthrough. the-chain 28 to-the shaft 25 to rotate the clutch operating frame 72 and to f simultaneously operate the shaft 37,

throughV the gear transmissionwhich includes the gears 34, 35 and 36. The shaft 37 can be rotated in kone direction or thel other by reversing thegears 35 "and 36. This is of coursey The` .shaft 19 through the rGeneva movement 24 imparts intermittent motion to the chuck' accomplished bythe hand lever 39..

mandrels and 7 7 so that when the tubeV 10 is being rotated, no power is being transmittedto the punch press 6 as the clutchjpulvley 61 'is disengaged from the shaft 58 (see Fig. 2). .lVhen the Geneva movement device reaches a predetermined position, the punching mechanism will be released for operation,

while the feed means remains stationary.

The shaft 3? in operation feeds the carriage supporting the'punch press,'motor and fin strip reel so that the formed fin strip will be properely convoluted -on the radiator tube 10 Y Y o Y. s

2. Aradiator tube fm winding machine comprising a rotarymount for a radiator through Vwhich thefin blankis .'paid, clutch means .for the said punch press, and automatic meansy for operating the clutch at certain intervals. K

'3. A `radiator tube iin winding machine comprising a rotary mount for a radiator tube, a slidable carriage, a fin blank reel on the carriage, a punch press on the carriage Icomprising a rotary mount for a radiator tube, aslidable carriage, a fin blank reel on the" carriage, a punch press on the carriage through which the fin blank is paid, clutch means for the said punch press, means for feeding the said carriage, said means including reversing gears whereby the carriage can be driven in reversed directions.

6. A radiator lin winding machine comprising a rotary mount for supporting a radiator tube, a slidable carriage, a iin blank supply reel on the carriage, a punch press on the carriage interposed between the reel and the tube mount, clutch means for operating i the punch press at certain spaced intervals, and means for rotating the tube mount when the punch press is inactive.

7. A radiator fin winding machine comprising a rotary mount for supporting araldiator tube, a slidable carriage, a iin blank supply reel on the carriage, a punch press on the carriage interposed betweenthe reel and the tube mount, clutch means for operating the punch press at certain spaced intervals, i" `means for rotating the tube mount when the punch press is inactive, including an eccentric movement device for intermittently operating the tube mount.

In testimony whereof I aflix my signature.
